[PATCH] shell script error management in ash (set of 6 patches)

[Roberto A. Foglietta]

Hi all,

 I will send the whole six patches developed in these days with the test
suite in a tarball.

busybox-1.33.1-1of6-add-trap-ERR-to-ash.patch
busybox-1.33.1-2of6-trap-ERR-fix-global-LINENO.patch
busybox-1.33.1-3of6-set-E-error-trace-added.patch
busybox-1.33.1-4of6-global-FUNCNAME.patch
busybox-1.33.1-5of6-multiline-trap-LINENO-bugfix.patch
busybox-1.33.1-6of6-when-FUNCNAME-is-null-bugfix.patch

 The whole set enanches the shell script management in ash (compatible with
bash)

 Best regards,
